The new reputation graph is nice and the gray line at 200rep is also useful. However it would be great when the different forms of reputation (votes, accepted answers, bounties, ...) would be colored differently. Especially the two groups of capped rep (votes, +2 for wiki edits, ...) and uncapped rep (accepted answers, bounties, ...) should be separated.
Here the idea: The capped rep should be colored differently and be always on bottom on the bar graph. This way someone can see how far it is away from the daily rep limit. The uncapped rep is on top and can peak over the 200rep limit. There should also be an indicator whether the rep cap was hit and therefore counts for the Epic and Legendary badge. For example the gray line at 200rep could be thicker for that day.
Also: The reputation lost because of the reputation limit could be displayed as gray bar on the very top of all other rep. Seeing this would be also a nice piece of information.
The reputation which disappeared because it has been used as a bounty should also be displayed accordantly and not simply subtracted. For example if someone received 180 rep on one day and sets out a bounty of 200 rep the graph should display two bars one positive to 180 to indicate the achieved rep of the day and one negative to -20 to indicate the final rep. The positive bar should be in a (slightly?) different color than normal to indicate its "received but given away" status. A simple example would be a yellow positive bar and an orange (instead red) negative one. If the total rep was positive (e.g. 225 rep - 200 rep bounty) there could be a normal positive bar with 25 points and then on top the yellow one from 25-225. Otherwise bounties would look more like penalties.
